Problems solved by technology
[0003] During the test, due to manual shaking of the two-way hand pump, the speed cannot be kept constant, and the output flow of the two-way hand pump is very small (<0.5L / min), which makes it impossible to measure accurately with ordinary flowmeters, so it is necessary to use the total output The flow calculation is the average output flow of the bidirectional hand pump, but it is easy to make mistakes due to manual counting of the number of hand pump rotations, so it is necessary to provide a method that can detect the manual shaking of the bidirectional hand pump to obtain the output flow of the bidirectional hand pump

Embodiment Construction
[0033] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.
[0034]After the applicant's research and analysis, the reason for the problem that ordinary flowmeters cannot accurately measure the two-way hand pump is that the manual shaking of the two-way hand pump can not keep the speed constant, and the output flow of the two-way hand pump is very small (<0.5L / min), and this problem is unavoidable during human operation, so the flow rate of the two-way hand pump cannot be detected by ordinary flowmeters, so the present invention uses the total output flow to calculate the average output flow of the two-way hand pump. me...

The detection equipment for the two-way hand pump comprises the two-way hand pump, a two-way speed regulating system rotatably connected with the two-way hand pump, a hydraulic system communicating with the two-way hand pump and an electric appliance control cabinet connected with the two-way speed regulating system and the hydraulic system, wherein the two-way speed regulating system comprises a speed reducer rotatably connected with the two-way hand pump, a speed regulating motor rotatably connected with the input end of the speed reducer and an encoder connected with the speed regulating motor; and the hydraulic system comprises a direction control set communicating with the two-way hand pump, anoverflow valve connected with an oil outlet of the direction control set in series, a measuring cup communicating with the oil outlet of the direction control set and an oil outlet of the overflow valve, an oil tank communicating with the direction control set and a pressure gage connected between the two-way hand pump and the overflow valve in parallel. The detection equipment and the detectionmethod can avoid errors caused by manual operation and accurately measure output flow and pressure values of the two-way hand pump under different working conditions.
Description
technical field [0001] The invention relates to the field of detection of hydraulic pumps, in particular to a detection device and a detection method for a bidirectional hand pump. Background technique [0002] As a hydraulic pump that can provide power to the hydraulic system to drive the actuator manually when the main oil source such as the motor in the hydraulic system fails, the bidirectional hand pump needs to be guaranteed to be able to operate under the condition of human drive The hydraulic system provides sufficient pressure and flow, so it is necessary to detect the output pressure and flow under different working conditions. [0003] During the test, due to manual shaking of the two-way hand pump, the speed cannot be kept constant, and the output flow of the two-way hand pump is very small (<0.5L / min), which makes it impossible to measure accurately with ordinary flowmeters, so it is necessary to use the total output The flow calculation is the average output...
